This invention relates to new and useful improvements in a reversible window pane with a window sash.

More specifically, the invention proposes the novel construction of a window sash having a window pane reversibly supported within the window frame to permit the outside thereof to be extended inwards when desired to permit cleaning the Windows without requiring projecting any portion of the body to the outside of the building structure.

A further object of the invention proposes characterizing the sash member by a rectangular opening within which a U-shaped bracket is pivotally supported along its back side with its arms extending freely therefrom to pivotally support a frame enclosing a window pane to permit the frame enclosing the pane to be pulled out of its position in the rectangular opening to be pivoted relative to the arms.

Still another object of the invention proposes arranging the U-shaped bracket in a manner to pivot either vertically or horizontally depending upon the direction in which it is desired to have the frame enclosing the window pane move.

Still another object of the invention proposes arranging a novel means for retaining the frame enclosing the window pane against pivoting relative to the U-shaped bracket until such time as the locking means has been freed permitting such pivoting.

It is a further object of this invention to construct a reversible window pane within a window sash, which is simple and durable and which may be manufactured to be applied to a window structure at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in Which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a front elevational view of a pair of superimposed window sashes provided with reversible window panes constructed in accordance with this invention.

Fig. 2 is a perspective View similar to Fig. 1 but illustrating a partially opened position of the Window panes.

Fig. 3 is a view similar to Fig. 2 but illustrating the sashes mounted in an outer frame and still further open position of the window panes.

Fig. 4 is a perspective View of one of the rever- -on the line 5 5 of Fig. 2.

Fig. 6 is a plan View of Fig. 5 looking to the direction of line 6 6 of Fig. 5.

Fig. 'l is an enlarged partial horizontal sectional view taken on the line 'I-l of Fig. 1.

Fig. 8 is a View similar to Fig. 7 but illustrating an unlocked position of the parts.

The reversible window, according to this invention, includes a sash member II) having a rectangular opening for a window pane I2 mounted in a suitable frame I'I. On the drawings the window is characterized by a pair of window sashes constructed in the conventional manner toy slide vertically in an outer frame shown partially at I Ila in Fig. 3. Each of the sashes is alike in construction and diiers merely in the manner of supporting the window frame I1.

The frame I1 of the lower sash I0 is arranged to pivot horizontally while the frame I'I in the upper sash is arranged to pivot vertically. In view of these similarities in construction the details of one of the frames I 'I will be given in this specification and it should be understood that the details likewise apply to the other frame I1.

A U-shaped bracket I3 has its back I4 extending along one side of the rectangular opening I I and its arms I5 extending along the adjacent sides of the rectangular opening. A hinge plate I6 extends along the back I4 of the U-shaped bracket I3 and the adjacent edges of the hinge plate I6 andthe back I4 are pivotally connected together to provide a pivotal support for the U-shaped bracket I3. The hinge plate I6 is securely attached to the material of the sashl I0 adjacent'the side of the rectangular opening II and provides a hinge permitting the bracket I3 to be turned to extend its arms I5 from the rectangular opening as shown in Figs. 2 and 3.

The frame I'I is set into the rectangular opening II and into the U-shaped bracket I 3. Pins I8 turnably connect the free ends of the arms I5 to the sides of the frame I1 to pivotally support the frame I1 and the window pane I2. A

Means is provided for restraining the frame I1 against being pivoted relative to the arms I5 except when the U-shaped bracket I5 is pivoted to the position illustrated in Fig. 2. This means comprises a pin I9, mounted on the frame I l, which is adapted to engage in a complementary opening 20 formed in the back I4 of the U-shaped bracket I3 to. hold the frame against pivoting. Means is provided for slightly laterally slidably 3 supporting the frame I1 relative to the bracket I3 to permit movement to the position illustrated in Fig. 8 to disengage the pin I9 from the opening 20 to free the frame I'I to pivot.

To accomplish this the pivot pins I8 are turnably extended through the arms I of the U- shaped bracket I3 and have their inner ends xedly attached to blocks 2| slidably mounted within a complementary recess 22 formed in the frame I'I. An expansion spring 23 is also mounted within the recess 22 to operate between the block 2I and the end wall of the recess 22 to urge the frame I1 into a position in which the pin I9 will retain an engaged position with the opening 20. However, when the frame is pivoted vto the position shown in Fig. 2 it may be moved slightly laterally of the U-shapedi bracket I3-to disengage the pin I9 from the opening 20 as illustrated in Fig. 8. This lateral movement will free the frame I'I to be pivoted relative to the U- shaped bracket I 3 and into the position illustrated in Fig. 3. To return the frame l'I'to its engaged position with the U-shaped bracket I3 it is merely necessary to reverse the above procedure. It is to be `.understood that each side of the supporting frame I'IV must be slidably mounted in a manner outlined to permit the disengagement of the pin i9 from the opening 20. K
